Fluke PT12 Liquid Level Sensor Probe Pilot Tube

Product Description

The FLUKE PT12 is a liquid level sensor and probe pilot tube designed for accurate fluid measurement in HVAC and mechanical system diagnostics. With an overall length of 12 inches, it provides sufficient reach for accessing fluid chambers and flow measurement points in a range of field applications. This probe is used alongside a compatible air flow meter and is typically installed or swapped out by HVAC technicians and mechanical service professionals performing system diagnostics or routine instrumentation maintenance. At 0.37 pounds, the PT12 is a compact, lightweight accessory that stores and travels easily in a field service kit.

The PT12 is suited for use in commercial and residential HVAC service scenarios where liquid level sensing or pilot tube measurements are required. It serves as an accessory probe for Fluke air flow meter equipment, enabling techs to extend measurement capability without carrying separate instrumentation. This probe is a direct-use accessory in flow measurement setups and is well-suited to mechanical rooms, air handling units, and ductwork diagnostic work where precise readings are critical.
